I said in your other thread that I wondered if scientists had come out with man-accelerated climate change, rather than man-made if it would have changed the debate. What are your thoughts on that, or do you think our contributions have nothing to do with the environment?

possibley
do we humans pollute...yes
do we humans waste...yes
do we humans overdevelop and cut trees(a natural radiant cooler and co2 user/o2 PRODUCER)...yes
are we humans the cause of the earths climate changes........NO
I live right on the shore on Long Island...long Island was CREATED by the last glaciers.....did we CAUSE the warming 10's of thousands of years ago to melt the glaciers????
look at the chart..temps vary..but are all still with in range
do you DENY that the SUN has an effect on the earths temps???????
I have lived in my house for over 25 years....
and the sea level has not changed much at all, if fact if you look at the old dock (very old about 75 years old) I'd say the sea levels have DROPPED a little
The most recent glaciation began about 125,000 years ago and climaxed about 21,000 years ago. At this time, over 30% of the earth’s surface was covered by ice, and sea level was at least 125 meters lower than present
even in acient greece and rome they talked about climate change:::
The ancient Greek philosopher Plato, who lived in 427-347 BC, wrote about major climate changes known in his day. In the dialogue, "Timaeus," he argued global warming occurs at regular intervals, often leading to great floods. Said Plato, "When... the gods purge the Earth with a deluge of water, the survivors... are herdsmen and shepherds who dwell on the mountains. But those who... live in cities are carried by the rivers into the sea."
In the dialogue, "Critias," Plato wrote about weather-related geological changes. He referred to "formidable deluges" that washed away all the top soil, turning the land into a "skeleton of a body wasted by disease." What were now plains had once been covered with rich soil, Plato said, and barren mountains were once covered with trees. The yearly "water from Zeus" had been lost, he went on, creating deserts where the land was once productive.
Plato's student, Aristotle, who lived from 384 BC to 322 BC, also recorded evidence of global warming in his work, "Meteorologica." He noted that in the time of the Trojan War, the land of Argos was marshy and unarable, while that of Mycenae was temperate and fertile. "But now the opposite is the case," Aristotle wrote. "The land of Mycenae has become completely dry and barren, while the Argive land that was formerly barren, owing to the water has now become fruitful." He observed the same phenomenon elsewhere covering large regions and nations.
Theophrastus, a student of Aristotle who lived 374-287 BC, discussed climate change in his work, "De ventis," which means "The Wind." He observed that in Crete, "nowadays the winters are more severe and more snow falls." In earlier times, he said, the mountains there bore grain and fruit, and the island was more populous. But when the climate changed, the land became infertile. In his book, "De causis plantarum," Theophrastus noted the Greek city of Larissa once had plentiful olive trees but that falling temperatures killed them all.
In the first century AD, an ancient Roman named Columella wrote an agricultural treatise called, "De re rustica." In it, he discussed global warming that had turned areas once too cold for agriculture into thriving farm communities. Columella cites an authority named Saserna who recorded many such cases. According to Saserna, "regions which formerly, because of the unremitting severity of winter, could not safeguard any shoot of the vine or the olive planted in them, now that the earlier coldness has abated and weather is becoming more clement, produce olive harvests and the vintages of Bacchus [wine] in greatest abundance."
In the Middle Ages, people began recording the temperature and climate-related phenomena, such as the dates when plants began to blossom annually. They were aware of a warming trend that began around 900 and a cooling trend that began around 1300. We know that during the warm period, the Vikings established settlements in Greenland where perpetual ice had previously covered the land. Ancient Norse records tell us these settlements were abandoned after 1250 when falling temperatures made farming less viable and spreading ice in the sea made transportation more difficult.
The cooling trend led to heavy rains in 14th century Europe that were too much for the crops, leading to reduced agricultural output and numerous famines. In the 15th century, a warming trend returned, which lasted until the middle of the 16th century when temperatures again started to fall. By the 17th century, it was clearly apparent that a cooling trend was altering sea routes, changing the kinds of crops farmers could grow, fishing patterns and so on. Glaciers began to advance rapidly in many places and rivers that had long been ice-free year round started to freeze in the winter. This "little ice age" continued well into the 19th century.
Since then, we have been in a warming cycle that appears to have accelerated around 1950. The point is that we know a great deal about climate changes from the historical record and need not rely solely on scientific studies of core samples, tree rings and so on. These changes occurred long before industrialization and could not possibly have been man-made in any way. They don't prove man is not now affecting the climate through carbon dioxide emissions, but they do tell us temporary warming trends are common in human history. It may only be a matter of time before another cooling trend comes along.
you see the problem,,we are not saying that there is no such thing as global warming/cooling...we are saying that it is a NATURAL OCCURANCE.....The simple FACT is, to say its 'man-made' is just a LIE........do we humans help/hinder it.???..certainly.....................but we are not the CAUSE
